EDIT:Oh c**p, I found a buglet, an annoying one. It was a seamingly harmless change that I made to a script just before uploading. Easy to fix: Open /usr/bin/gtkdialog-splash in a text editor -- look at line 244, there is a "-" missing, it should be "yaf-splash". This bug prevents some popup progress indicators to display.
Note, I'll probably re-upload Quirky 1.2 tomorrow (but it will be done in such a way not to break any downloads in progress).

EDIT:Decided had better do it as soon as possible, so it is done. Fixed ISOs now uploaded.

A technical note for Lupu developers: Woof searches for PETs in the order Packages-puppy-5-official Packages-puppy-quirky-official Packages-puppy-woof-official Packages-puppy-4-official.
An "architecture independent" PET such as pprocess will be found in the Quirky repo and used. So, you don't have to worry about putting it into the puppy-5 repo.
